Description

Technical Field

[0001] This utility model relates to the technical field of corner connection components, specifically a rotatable and adjustable cable tray corner connection component with quick disassembly function. Background Technology

[0002] In cabling systems for power, telecommunications, and building applications, cable trays serve as crucial supports and protection for cables. Their installation directly impacts cable laying quality, lifespan, and ease of maintenance. Due to the complexity of actual cabling environments, the routing of cable trays often needs to be adjusted according to spatial layout; therefore, the design of corner connections becomes a critical aspect of cable tray systems.

[0003] Traditional cable tray corner connections often use fixed-angle connectors, such as right-angle elbows and angled joints. While these connectors can meet basic turning requirements, they have significant limitations: First, the fixed-angle design makes them unsuitable for diverse installation scenarios. When the corner angle needs to be adjusted on-site, different connector specifications must be replaced, increasing spare parts inventory costs and extending the construction period. Second, some fixed connectors have poor sealing between themselves and the cable tray body. Over long-term use, gaps can easily appear, allowing dust, moisture, and other debris to enter the cable tray, affecting cable insulation performance. This can even cause cables to detach from the gaps due to external forces, posing a safety hazard.

[0004] In addition, some traditional angle-adjustable corner structures often have openings at the joints during the adjustment process, requiring repair and hindering angle adjustment. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a rotatable and adjustable cable tray corner connection assembly with quick disassembly function.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A rotatable and adjustable cable tray corner connection assembly with quick-release function includes:

[0008] A pair of cable tray sections, the ends of which are rotatably connected by a connector;

[0009] The connector includes:

[0010] A pair of arc-shaped plates are respectively fixedly connected to the ends of the pair of cable tray sections, and the pair of arc-shaped plates are rotatably connected to each other at the axis.

[0011] An elastic sheet is fixed to the bottom wall of one end of one of the cable tray sections;

[0012] U-shaped clamping sleeve, fixed to the bottom wall of the other end of the cable tray section;

[0013] One end of the elastic sheet is slidably inserted into the U-shaped sleeve; when the pair of arc plates rotate relative to each other, they drive the pair of cable tray sections to rotate relative to each other. The elastic sheet slides in the U-shaped sleeve and undergoes elastic deformation. The deformed elastic sheet cooperates with the U-shaped sleeve to form an arc-shaped sealing structure that seals the gap between the ends of the cable tray sections.

[0014] Preferably, the free end of the elastic sheet has a threaded hole, and the U-shaped sleeve has an elongated adjustment hole at the position corresponding to the threaded hole. A bolt is screwed into the threaded hole, and there is a gap between the bolt and the bottom wall of the U-shaped sleeve.

[0015] Preferably, the elastic sheet is configured such that when a pair of cable tray sections rotate to a vertical position, the elastic sheet is at the maximum stroke of the U-shaped ferrule.

[0016] Preferably, the width of the elastic sheet is greater than the width of the cable placement cavity at the end of the cable tray section where it is fixed, and the elastic sheet covers a portion of the opening of the cable placement cavity below the end of the cable tray section where it is fixed in its natural state.

[0017] Preferably, the pair of arc-shaped plates are connected by a quick-connect hinge.

[0018] Preferably, the pair of arc-shaped plates are semi-circular plates, and the elastic sheet is made of spring steel.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. Effectively seals gaps and ensures safety: The elastic sheet and U-shaped clamp work together. When the cable tray sections rotate relative to each other, the elastic sheet deforms and forms an arc-shaped sealing structure, which can effectively seal the gap between the ends of the two cable tray sections: prevents debris from entering the cable tray, avoids cables from falling out of the gap, and ensures the safe laying of cables.

[0021] 2. Flexible and adjustable angle: Through the rotational connection of a pair of arc plates and quick-connect shaft, the angle of the cable tray section can be flexibly adjusted according to different installation scenarios to adapt to diverse installation environments.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0029] Example

[0030] like Figure 1-4 As shown, a rotatable adjustable cable tray corner connection assembly with quick-release function includes:

[0031] Cable tray section 1: A pair of cable tray sections 1 are the main channels for cable laying, used to carry and protect cables. Their ends are rotatably connected by connectors, providing a basis for angle adjustment.

[0032] Arc-shaped plate 2: A pair of arc-shaped plates 2 are fixedly connected to the ends of a pair of cable tray sections 1, and are rotatably connected to each other at the axis, specifically through a quick-connect swivel. The arc-shaped plates 2 are semi-circular plates, and their cooperation allows the pair of cable tray sections 1 to rotate relative to each other, thereby achieving angle adjustment.

[0033] Elastic plate 3: The elastic plate 3 is made of spring steel and is fixed to the bottom wall of one end of one of the cable tray sections 1. Its width is greater than the width of the cable placement cavity at the end of the cable tray section 1 where it is fixed. In its natural state, it covers part of the opening of the cable placement cavity below the end of the cable tray section 1 where it is fixed, which can provide a certain degree of shielding and protection for the cable. When the pair of cable tray sections 1 rotate relative to each other, one end of the elastic plate 3 slides in the U-shaped sleeve 4 and undergoes elastic deformation. The deformed elastic plate 3 and the U-shaped sleeve 4 cooperate to form an arc-shaped sealing structure that seals the gap between the ends of the pair of cable tray sections 1, preventing foreign objects from entering or cables from falling off. In addition, the free end of the elastic plate 3 has a threaded hole for engagement with bolts. And when the pair of cable tray sections 1 rotate to a vertical position, the elastic plate 3 is at the maximum stroke of the U-shaped sleeve 4.

[0034] U-shaped clamp 4: The U-shaped clamp 4 is fixed to the bottom wall of the end of another cable tray section 1, and is used to accommodate one end of the elastic piece 3 and guide its sliding. The U-shaped clamp 4 has an elongated adjustment hole at the position corresponding to the threaded hole of the elastic piece 3. A bolt is screwed into the threaded hole, and a gap is left between the bolt and the bottom wall of the U-shaped clamp 4. This structure can help fix the position of the elastic piece 3, while not affecting its sliding adjustment within a certain range. The bolt can prevent the elastic piece 3 from falling out of the U-shaped clamp 4 when the cable tray section 1 is adjusted.

[0035] A pair of cable tray sections 1 serve as the main channels for cable laying, and their ends are rotatably connected by a connector consisting of a pair of arc-shaped plates 2. The arc-shaped plates 2 are semi-circular plates, fixed to the ends of the pair of cable tray sections 1 respectively, and rotatably connected at their centers via a quick-connect shaft. When it is necessary to adjust the angle of the cable trays, rotating the pair of cable tray sections 1 will cause the pair of arc-shaped plates 2 to rotate relative to each other around the quick-connect shaft, thereby achieving flexible adjustment of the angle to meet the needs of different installation scenarios.

[0036] During the angle adjustment process, the elastic plate 3 and the U-shaped clamp 4 cooperate. The elastic plate 3, made of spring steel, is fixed to the bottom wall of one end of the cable tray section 1, and one end of it is slidably inserted into the U-shaped clamp 4 fixed to the bottom wall of the other end of the cable tray section 1. When the pair of cable tray sections 1 rotate relative to each other, the elastic plate 3 slides within the U-shaped clamp 4 as the cable tray section 1 rotates, and undergoes elastic deformation due to the constraint of the U-shaped clamp 4. Since the width of the elastic plate 3 is greater than the width of the cable placement cavity at the end of the cable tray section 1 where it is fixed, and it naturally covers part of the opening of the cable placement cavity, the deformed elastic plate 3 and the U-shaped clamp 4 cooperate to form an arc-shaped sealing structure, which can effectively seal the gap between the ends of the pair of cable tray sections 1, prevent debris from entering the cable tray or the cable from falling out of the gap, and ensure the safe laying of the cable.

[0037] Meanwhile, the threaded hole at the free end of the elastic plate 3 is bolted to the elongated adjustment hole on the U-shaped sleeve 4, with a gap between the bolt and the bottom wall of the U-shaped sleeve 4. This structure does not affect the sliding adjustment of the elastic plate 3 within the U-shaped sleeve 4, and after adjustment to the required angle, tightening the bolt helps to fix the position of the elastic plate 3, maintaining a stable rotation angle. It also prevents the elastic plate 3 from falling out of the U-shaped sleeve 4 during adjustment of the cable tray section 1. When a pair of cable tray sections 1 rotate to a vertical position, the elastic plate 3 is at the maximum stroke of the U-shaped sleeve 4, at which point the elastic deformation reaches its maximum, still reliably achieving functions such as sealing.

[0038] When disassembly is required, simply unscrew the bolts, slide the elastic piece 3 out of the U-shaped sleeve 4, and then disconnect the quick-connect shaft between the pair of arc plates 2 to achieve quick separation of the pair of cable tray sections 1, demonstrating the function of quick disassembly.

[0039] The angle of rotation is flexible and adjustable: Through the rotational connection between a pair of arc plates 2 and the quick-connect shaft, the angle of rotation of the cable tray section 1 can be flexibly adjusted according to different installation scenarios to adapt to various installation environments.

[0040] Effectively seals gaps and ensures safety: The elastic sheet 3 cooperates with the U-shaped sleeve 4. When the cable tray section 1 rotates relative to each other, the elastic sheet 3 deforms and forms an arc-shaped sealing structure, which can effectively seal the gap between the ends of the two cable tray sections.

[0041] Prevent debris from entering the cable tray, avoid cables from falling out of gaps, and ensure safe cable laying.

[0042] Stable and controllable rotation angle: The threaded hole at the free end of the elastic plate 3 and the elongated adjustment hole of the U-shaped sleeve 4 are connected by bolts. After adjusting to the required angle, tightening the bolts can help fix the position of the elastic plate 3 and keep the rotation angle stable.

[0043] To prevent components from falling off: The mating structure between the bolt and the U-shaped clamp 4 can prevent the elastic piece 3 from falling off the U-shaped clamp 4 during the adjustment of the cable tray section 1, thus ensuring structural stability.

[0044] Adaptable to extreme angles and reliable function: When the cable tray section 1 rotates to the vertical state (at the maximum stroke), the elastic sheet 3 can still reliably perform functions such as sealing when the deformation reaches its maximum, making it highly applicable.

[0045] Quick disassembly is achieved: during disassembly, simply unscrew the bolts, slide out the elastic piece 3, and disconnect the quick-connect shaft to quickly separate the two sections of the cable tray 1. The operation is convenient and improves disassembly efficiency.

[0046] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
